solid subframe mounts - pros/cons

[silver7]

any advice/experience appreciated on solid subframe mounts. Only downside so far seems to be a bit more noise? Help appreciated

Do it, they transformed the control on my 993 RS clone, much much better on the track. (I presume you mean the rear subframe mounts). Check out rennlist, lots of threads on the subject. Mine were fitted by 9m after recommendation by Colin. Noiticed no difference to ride (I have PSS9's and RS a/r bars) but big difference on the track. Basically the car doesn't try and steer itself, which is good as you can control it much better if it starts to drift back steps out.

ok thanks, yes I do mean rear subframe mounts, I believe they are a GT2 evo part, part number would be appreciated if anyone has it! They sound like a good mod

They are a good mod if you have circuits etc in mind,if its for mainly road leave as standard.The rs has stiffer rubber mounts than a standard 993.You need to watch for cracking on the chassis leg where they mount,i have seen three cars so far with this.My X cup car had cracked in 2 places,granted it was banged over curbs during races etc ,but the road can give you car more grief!

thanks Paul, It is used mostly for track but also about 1500 road miles a year. That sounds like a big downside. Do the standard RS mounts wear?

 

[paul howells]

I changed my mounts after the car had done about 40,000 miles.and about 8 years old.
They were not worn at all.They dont get a lot of movement/wear
My 993gt2 that i had was a rhd road car,which was fitted with solid mounts from new.
FVD supply the kits

I have the solid mounts and they do tranform the car.

I think uprating anything causes a circle of issues.

I took the view that in relation to the road use I do I tend to keep out of potholes and rarely ever give it grief on the road. The rest is driving to trackdays/Ring which is often motorway.

When on track I always try to keep off kerbs to save giving any of the suspension too much grief; I am not there to put in times.

Again I think they were in GT2 evos which were road cars so I imagine Porsche scoped out this issue?

 

[silver7]

thats a good point Richard. Do GT2 EVO's have any problems running this part?

mine has the solid mounts Julian, as you had a few laps at Oulton you will know the difference on the track !

 

[silver7]

Steve - I might have guessed you would have them! - I do have a fear of this cracked chassis though. Any issues so far?

 

[paul howells]

Silver as people say they are good,but you need to keep a eye on the mounting points,if you start running stiffer dampers and springs etc,then all puts extra stress on the points.
Its also a fairly big job,and complete reset of geo etc,i would also recommend doing the front lower bushes as well,but not solid or rose joints for the road.
If you dont drive the car that hard,the car is very good standard,also lowering the car stiffens things up a fair bit.
When i done my car ,it was certainly tighter and more responsive,especially to throttle steering,it felt like a 964!
Also make sure your lsd is in good order,its a slippery slope once your on it!!!

Thanks Paul. Well the car is going in for KW3 clubsports, new rear a arms, rear control arms, front balljoints and chris walrod front wishbone bushes, as well as motorsport LSD plates. If I get the mounts done now it isn't too bad a job. What do you think? would the KW3 clubsports make the possibility of cracks greater? Thanks again

Julian no issues so far, having said that the rs is tracked far less than most of the guys on here so the chassis is exposed
to far less stress levels, will digest what Paul has mentioned, MOT due and will have a good visual on the ramps.

thanks Steve, I am sure it will be fine!
